Scientists have recently discovered that the ultrathin（超薄的）, layered（分层的） construction of a butterfly’s wings, the same as the one making some butterflies shimmer （投影）via（通过）the phenomenon of iridescence（彩虹现象）, are enabling the insect to control how much heat energy is absorbed by its wings and how much is reflected away.

1. wings, the same as the one making some butterflies shimmer via the phenomenon of iridescence, are enabling
2. wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables
3. wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling
4. wings—the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enables
5. wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable

                                                           Answer:A

想不通为何是are enabling 主语不是the construction吗？难道是whings后面省了that?

顶

以前看讨论说the one只能指代人，对吗？麻烦NN解释一下这句的意思

怎么没有NN解答呢？而且我还不明白为何用现在进行时，are enabling？

the same as the one making some butterflies shimmer via the phenomenon of iridescence, 是插入语可以不考虑， are enabling。。。and how much is reflected away应该是have recently discoverd的宾语，发现是一个事实那也应该用一般现在时啊？
